Potential problems:

 * <pkg>_EXTRA_DOWNLOADS downloads from the same <pkg>_SITE that is
   used to download <pkg>_SOURCE. So if your tarball and license files
   are not at the same location, it won't work. This could be fixed by
   having <pkg>_EXTRA_DOWNLOADS use a full path rather than relying on
   <pkg>_SITE.

 * <pkg>_EXTRA_DOWNLOADS = foo will download the file as "foo" in the
   download directory. However, I do expect many of the license files
   that you would download this way to have relatively similar names:
   COPYING, LICENSE, Copyright, or something like that. And therefore,
   if two different packages have <pkg>_EXTRA_DOWNLOADS =
   http://someplace/COPYING, the COPYING files would overwrite each
   other in the download directory.

Best regards,

Thomas
